Claudia Schiffer (1970-)

Schiffer(pronounce: Shiffuh) and
Schwarzenegger(Shwartsenegguh) and
Schumacher(Shoomahhhuh)
taught people to pronounce
the German `Sch' just like the English `Sh',
and the ending `er' more or less like the English `uh'.

Thus they earned the eternal gratitude of
other ex-pats with weird German names, such as
Schmidhuber(Shmidhoobuh).
